The Micron MT58L64L32PT-6TR is a 2Mbit synchronous SRAM from the SYNCBURST™ family, organized as 64K words by 32 bits. It delivers a 3.5 ns access time and runs at a 166 MHz clock, making it a fit for high-bandwidth data paths in networking, telecom, and DSP applications where the processor needs a wide, fast scratchpad or packet buffer. The parallel interface and 32-bit data bus suit it for glue-less connection to a wide range of ASICs, FPGAs, and RISC processors that expect a synchronous SRAM controller. The 100-pin TQFP package keeps the footprint manageable for a 32-bit wide memory on a multi-layer PCB.
At 3.5 ns access time, this part can feed a 166 MHz bus with zero wait states on back-to-back reads, provided the controller meets the setup/hold window. That timing margin is tight — board-level signal integrity matters: keep trace lengths matched and terminate the clock line.
